Most fat-soluble nutrients are absorbed in the _______ system. Question 19 options: vascular lymphatic neurological adrenal
Leya [2.2K]

Most fat-soluble nutrients are absorbed in the Lymphatic system.

<h3>What is Lymphatic System?</h3>

A network of tissues, veins, and organs known as the lymphatic system collaborates to transport lymph, a colorless, watery fluid, back into your circulatory system (your bloodstream).

Your body's arteries, smaller arteriole blood vessels, and capillaries each day carry about 20 liters of plasma. About 17 liters are then returned to the circulation through veins after providing nourishment to the body's cells and tissues and collecting their waste products. The remaining three liters permeate your body's tissues via capillaries. The lymphatic system gathers this extra fluid, which is now known as lymph, from your body's tissues and transports it to various locations before returning it to your bloodstream.

In a certain population of wolves, a mutation takes place and several wolves
Valentin [98]

Answer:

According to the theory of evolution by natural selection wolves with mutations will outgrow the wolves without mutation.

Explanation:

Nature always poses challenges to the living organisms in various forms like climate change, food scarcity, natural disasters, etc. If an organism has a characteristic to survive better than the other, then they will be selected by the nature. We can also use the term fitness for this. Darwin also referred about this as reproductive fitness which means only those organisms which are fit in their environment produce more progeny and increase in number. s we can see that the introduction of mutation has added the advantage of being faster and stronger, so when it comes to competition for food the wolves with mutation can easily catch the predator than wolves without mutation. Since mutation has resulted in better adaptation to their environment they will outgrow in number.

Describe what happens to the air in the lungs when we breathe. What happens to the concentration of
Otrada [13]

When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.

Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.

Hope this helped, even if it helped a tiny bit. :)
